my petcock is under my tank and would like to make it gravity fead like a lawn mower or motorcycle.there must be a diaphame in there for the vacuum to work.plugging off the carb where the vacuum hose goes wouldn't work cause the diapham has to work off sucktion.should I find something in a hard ware store that screwes into the tank with a outlet and just plug the vacuum hole on carb
